Long term leakage control
Leaders in Sealing Integrity
Garlock Compression Packing
Compression Packing Products were once used to seal visible
leakage in valves and control leakage in pumps. Through
advancements in materials, design and technology, Garlock
is now able to seal the most difficult fugitive emissions and
eliminate pump leakage entirely.
Garlock compression packing products will contribute to
maintaining a safe process, meet stringent fugitive emission
limits and save resources, with proven reliability. Our product
will generate the greatest return on initial investment in
terms of leakage control, service life, dependability and
cost effectiveneess. We also provide expertise with highly
knowledgeable application engineering support. The Garlock
Compression Packing facility is committed to supplying the
highest quality engineered products to industry throughout the
world.
The facility also houses the Garlock Textile Division, where we
continue to research and develop new fiber blends to bring
customers a wide array of packings with optimum performance
characteristics.

Garlock Compression Packing
Valve Packing:
Fugitive Emissions Control Products
WHAT TO DO FOR EFFICIENT FUGITIVE
EMISSION CONTROL?
Fugitive emissions from valves are the largest contributor to
the fugitive emissions of any plant processing volatile organic
compounds (VOC) and hazardous air pollutants (HAP). A
majority of the fugitive emissions in petrochemical plants are
a result of valve gland leakage. This leakage, in most cases,
can be prevented with correct maintenance and with the use
of high performance compression packing.
WHAT IS THE ENHANCED LEAK DETECTION
AND REPAIR PROGRAM AND HOW CAN OUR
PRODUCTS AND EXPERTISE HELP?
Enhanced LDAR is used by the Environmental Protection
Agency (EPA), describing actions that plants must take to
attain and go beyond regulatory compliance. Enhanced LDAR
covers a number of elements such as quality control, training,
monitoring, repairs and most notably, equipment upgrades.
These upgrades include, requiring use of “low leak”* or low
emission (LE) compression packing. Garlock pioneered the
development of (LE) packing in the 1980s and has continued
to refine and widen its product offering through the years.
Our sealing solutions meet or exceed the requirements of
many recognized international standards and we offer our
limited performance warranty on these products. Our highly
trained technical support experts can help you find the most
appropriate solution and supply precious advice.
WARRANTY
Garlock will warranty that these sets will provide leakage
rates no greater than 100 ppm above background in VOC
service for a period of 5 years, when installed and maintained
in accordance with Garlock installation instructions and
warranty conditions**.
*Low-leak is defined as a valve with stem packing that carries a
warranty for 5 years able to deliver 100ppm leak performance.
Warranties are generally subject to valve conditions and installation
practices.

HOW TO INSTALL 212-ULE*
When packing a valve, pack 2 rings of “Packing B”, then one
ring of “Packing A”, then 2 additional rings of “Packing B”, giving
you a B-B-A-B-B configuration (or 212). This minimizes valve
emissions and reduces torque actuation forces. For stuffing

HIGH PURITY CARBON BUSHINGS
Our testing has determined that the optimal number of rings
to seal a valve stem is between 5 and 7. Any less than 5 rings
increases the chance of leaks, any more than 7 puts too much
drag on the stem. Garlock uses high purity carbon bushings
or Style 1998 EZ-Bushing to shorten deep stuffing boxes like
those that are typically found in older valves. When combined
with our radially expanding valve stem solutions, our high purity
bushings allow excellent sealing with low actuation force which
enables old, manual valves to be fit with air actuators and seal
like new. Further, our bushings are made to such exacting
material and dimensional standards that they can even be
certified for nuclear service.
Bushings can also be made from 1303-DRY. While this
approach adds some friction to the stem, it is an ideal choice
when the valve stuffing box depth cannot be determined prior
to repacking.

LIVE LOADING HARDWARE
Even with its densified graphite construction, an EVSP set
can consolidate by up to 2% over its service life. While this is not
an issue for valves that can be easily monitored and adjusted,
it does pose a problem for valves that are off the routine
maintenance path. Additionally some service conditions, like
severe temperature swings or frequent opening and closing,
can accelerate consolidation. Garlock’s solution for those types
of applications is Live Loading.
Live Loading can compensate for packing consolidation of
up to 3% and, when used with EVSP, can virtually eliminate
the need for adjustment. It does not however, put a constant
compressive force on the seal. If you use live loading with a
braided packing like 1303-FEP, it will significantly extend the
time between adjustments but adjustments will still be required.
We stock a wide range of spring washers so we can respond to
most needs within 48 hours.

GRAPH-LOCK® N STYLE 1398
Garlock style 1398 is a nuclear
grade braided flexible graphite
valve stem packing. The graphitecontaining Inconel filament adds
reinforcement to the packing to
handle BWR (General Electric) and
PWR (Westinghouse, Combustion
Engineering and Babcock Wilcox)
valve service conditions as an end-ring material for use with
other graphite products.
Style 1398 can also be used as a bushing material in the
bottom of the stuffing box to fill excess depth not needed for
sealing components.
